Dwyer Instruments DPG-100 Series Operating Instructions

The Series DPG-100 Digital Pressure Gage has a precise +/- 0.25%
full scale accuracy. The 4 digit digital display will reduce the potential for
errors in readings by eliminating parallax error commonly produced with
analog gages.
The DPG-100 is packaged in a durable extruded aluminum case
designed to meet NEMA 4/4X. The unit is battery powered and has an
auto-shut off to conserve battery life. A four button key pad allows easy
access to features without the need to work through complex menus or
difficult key combinations. These features include backlight, peak and
valley, auto zero and conversion of the pressure units. Readings may be
converted to various engineering units. See reverse page for available
units.
DPG Quick Start Button Operation
For complete detailed instructions on the four button operation see the
Operation Chart provided on back.
On/Backlight: Push to turn on; Press again for backlight.
Press and hold for 5 seconds to turn unit off.
Zero: Zeros the display - Push & hold for 2 seconds to zero
the display. If after pressing zero the display does not re-zero,
the unit is no longer meeting specified accuracy and should be
sent back to the factory for calibration. Do not use the zero
button when pressure is applied.
Units: Scroll (see next page for Model/Range Chart).
P/V: Peak recorded reading retrieved by initial push of button;
push again retrieves the valley or lowest value recorded.
INSTALLATION
When installing gage always use 1˝ hex at the base of the housing to
tighten the gage to a mating fitting. Do not apply wrench to housing.
MAINTENANCE
A "LOW BAT" descriptor indication will appear on the display when bat-
teries need to be replaced.
Battery Replacement: Remove the three screws on backplate. Lift back-
plate off by hand. Replace batteries per polarity indicators. To reassem-
ble, ensure O-Ring seats into housing evenly and press until seated
completely. Replace screws.
WARNING: Substitution of components may impair intrinsic safety.
Batteries must be changed in a non-hazardous location only. DO NOT
mix batteries from different manufacturers. DO NOT mix old batteries
with new batteries.

*Note: Gages with ceramic sensor are not CE and FM approved.
WARNING: DO NOT pressurize DPG over maximum allowable pressure
limits. Extreme damage can occur if limits are exceeded (see Pressure
Limit under Specifications). An overflow "OFL" designator will flash to
acknowledge that the gage's pressure range has been exceeded.
